Application fiIed December 23, 1925. Serial No. 77,276.

This invention relates to machines for use in the manufacture of boots and shoes for shaping uppers over lasts, and in some of 1t-s novel aspects has moreparticular reference to machines comprising in their organization means for pulling the upper over the last. The invention aims to provide improvements in means for performing various operations upon the work, including upperpulling, wiping and fastening operations, and me more general aspect has in view the provision of'a simple, compact and convenient arrangement of mechanisms for performing thedifferent Operations.

In accordance with one important feature of the invention novel means is provided for wiping the upper heightwise of the last, an operation frequently hereinafter termed the upwiping of the upper. The machine herein shown is provided with wipers forengagmg the upper in spaced locations at the end of the toe and at the opposite sides of the forepart respectively and for wiping the upper toward the edge of the last bot-tom while it is held under tension by the pulling means This serves to supplement the action of the pulling means by further tightening the upper over the last, and also to smooth the upper adjacent to the edge of the last bottom in preparation for the laying of its margin inwardly over the sole or insole. In the construction-herein illustrated the several wipers-are conveniently mounted on a single wiper carrier which is moved to effect the upwiping operation, and are moved relatively to the wiper carrier into and out of engagement wit-l1 the shoe. The invention further provides a novel arrangement of means for upwiping the upper andfor.

wiping its margin inwardly over the bottom of the last (herein termed the overwiping operation), the construction shown comprising an overwiping wiper adjacent to each of the upwiping wipers and operated through a lost motion connection by the same means which moves the upwiping wiper intoengagement with the shoe.

For pulling the upper over the last the invention provides novel gripper-operating means so constructed as to insure that the upper will be subjected to a predetermined tension without danger of an excess of tension such as might damage the upper.' For the purpose in view the construction .herein shown comprises, for operating each gripper,

a friction clutch-which is automatically controlled in such manner as to subject the upper to a definite degree of tension determined adj ustably by the pressure with which the 00- operating clutch members are held yieldingly in engagement with each other, and thento slip in response to resistance of the upper while holding it under the predetermined tension. Preferably also, as herein illustrated,

the co-operating clutch members are provided with serrated interengaging faces for subjecting the upper, in the relative slipping movement of the members, to repeated supplemental pulling impulses jwherebythe upper is stretched more effectively'to the required degree than by a single steady pull. For greater precision inregulating the force of the pull each clutclris connected directly and positively to its gripper." The machine herein shown comprises grippers'for pulling the upper respectively at the toe end and at the opposite sides of the forepart of the last, and has-a single spring control for both the side gripper clutches so as to equalize substan tially the forces applied in pulling the upper at the opposite sides.

For fastening the upper in pulled-over position the machine herein shown comprises mechanisms, including tack holders and drivers, for driving tacks or equivalent fastenings at the end and the sides of theforepart; and a further feature of the invention consists in novel means whereby delivery of tacks to the tack holders is facilitated. "While this feature of the invention does not depend for utility upon the driving of the tacks in any particular direction, it is especially useful in an organization such as herein shown in whichv the work is so positioned that-the tacks are I driven in substantiallyhorizontal d1rect1ons,

since inanorganization of that type therea're diiiiculties in theway of delivering tacks to the tack holders by gravity in the customary manher. For the purposes in view the invention provides for moving a tack holder into aposition at a substantial angle to the line of drive to receive a tack, the tack holders in the machine herein shown being turned from substantially horizontal driving positions into substantially vertical positions .to receive tacks delivered from above through their out let ends. The invention further provides-a convenient organization of mechanism" for moving each tack holder between its different responding tack driver are turned as a unit into and out of tack-receiving position in response to movement of a driver bar which op: crates the driver to drive the tack.

In addition to the above-mentioned features, the invention also provides a novel and convenient arrangement of operating instru- .mentahties, including separate toe and side grippers and upper-fastening mechanism positioned'between the side grippers, a novel shoe rest construction, and other novel details and combinations of parts, all of which will .be more particularly described by reference to the accompanying drawings and pointed out in the claims.

While the invention, in various novel aspects, is not limited as to the manner in which the shoe is positioned relatively to the operator of the machine, the machine herein shown is so constructed asto operate upon a shoe positioned with the bottom of its'forepart in a substantially vertical plane and its toe pointing upward in a substantially vertical direction, so that the top of the forepartof the upper is presented conveniently in view of the operator as he stands in front of the machine. For thus positioning the shoe, in

. the construction shown, there is secured upon the frame of themachine a bracket 20 having thereon a vertical arm 22 in the upper end of which are mounted for horizontal movements a pair of slides 24 arranged to eral and angular movements.

serve as rests for the toe endof the insole on thelast, the outer ends of. these slides having thereon forwardly extending projections arranged to overlap the edge of the insole and thus to assist in centralizing the shoe both lengthwise and laterally. The slides2i are provided with rack teeth arranged to engage respectively the opposite sides of a pinion 26 which is formed on a shaft 28 mounted in bearings in the arm 22, this shaft having on its lower end a knurled head 30 by which it may be turned to adjust the slides 2i sin'niltaneously toward or from each other for different widths of shoes. Secured to the shaft 28 are a pair of collars 32 between which is mounted a holder 34: having therein slideways' for another pair of slides 36 arranged to serve as rests for the bottom of the insole at or near the ball of the last and likewise having forwardly projecting end portions for overlapping the edge of the insole. The slides 36, 'like'the slides 2a, are provided with rack teeth arranged respectively to engage the opposite sides of another pinion 38 formed on the shaft 28, so that the slides 36 j are adjusted toward 'or'from each other simultaneously with the slides 24:. To accommodate the shoe rest to different lengths of shoes, the slides 36 are adjustable upward- 1y or downwardly by lengthwise movement ,9: of the shaft 28 in its bearings, the holder 34 being movable with the shaft since it is held between the fixed collars 32. In the knurled head 30 there are provided, as shown in Fig. 4, different series of depressions 40 at different levels to receive the end of spring-controlled plug 42 for holding the shaft 28 in different adjusted positions, in respect bothto its vertical movements and to itsturning movements. It will be seen that when the shaft 28 is properly adjusted the shoe positioned with substantial accuracy by the members 24 and 36 in respect to lengthwise, lat- For pulling the upper over the last there are provided grippers for gripping the upper respectively atthe end of the toe and at the opposite sides of the forepart. The toe gripper comprises a. gripper bar e4 which is mounted for horizontal sliding movements in a block 46 hereinafter more particularly referred to in connection with the wiping means. Fast on the bar l-l is an inner gripper 4:8, and pivotally mounted at 50 on the bar is an outer gripper jaw 52. The jaw 52, in the construction shown, is connected bv a link 54: to a rod 56 mounted for-lengthw r movements within the bar 44 for effecting closing and opening'movements of the jaw 52,

as more particularly hereinafter described, i although the invention is not dependent upon the use of the'particular means illustrated for controlling the closing and opening of the grippers. The bar 44 is extended rearwardly through a bracket 58 onthe frame and is provide'd at itsrear end with rack teeth engaged by a pinion 60 which is fast on a shaft 62. Also fast on the shaft 62 is the outer member 64 of a cone clutch, the innerinember 66 of which is rotatably mounted on the shaft 62 and has fast thereon a pinion 68 engaged by a. gearsector 70 formed 011 a lever 72. On the lower end of the lever 72 is a roll 74 engaged ly a cam formed in one side of a cam wheel 76 which is fast on a cam shaft 78. The clutch member 66 is held yieldingly in engagement with the member 64 by a spring 80,

the tension of which is adjustable by means of a hand wheel 82 threaded on the shaft 62. Itwill thus be seen that lengthwise upperpuiling movement is imparted to the gripper bar 44 through the clutch members 64 and 66 has been subjected by'the gripper to substantially the required tension. It will thus be seen that pulling movement is imparted positively to the gripper, until a predetermined degree of tension has been attained, whereupon the clutch begins to slip and by reason of the serrated formation of its interengaging faces imparts to the gripper a series of supplementary pulling impulses'until the operating member 72 arrives at the limit of its movement. Thereafter the gripper is held by the clutch with the upper under tension until the release of the upper is effected, as hereinafter described. lVhen the parts are returned to starting position, a lug 84 on the gripper bar 44 is carried into engagement with an adjustable stop 86 on the member 46 to determine the proper starting position of the gripper, and when the movement of the gripper bar 44 is thus stopped, the clutch member 66 slips relatively to the member 64 until it assumes its initial relation to the lat-- ter.

For closing the gripper on the upper there is provided in the bar 44 (Fig. 4) a spring 88 arranged to act on therod 56 to move the rod toward the left and thus to operate the link 54 with a toggle action to swing the jaw 52 toward the aw 48. In order to maintain the jaw 52 initially in open position, the rod 56 carries a pin 90 which projects through slots 92 in the opposite sides of the bar 44 in position to engage the block 46. It will be understood that when the gripper is returned to starting position, as hereinbefore described, the pin 90 is carried into engagen'i-ent with the bloclr 46 before the lug 84 engages the stop '86, whereupon movement of the rod isstopped and opening movement of the gripper is effected inresponse to the continued movement of the bar 44.

. For pulling the upper at the opposite sides of the forepart, the machine herein shown is provided with a single gripper at each side which is similar to the toe gripper in its construction and in the manner in which it is operated and controlled. Each ofthe opposite side grippers comprises a gripper bar 94 guided in an opening 95 (Fig. 2') in the block 46 and having thereon a fixed jaw 96 and a' pivoted j aw 98, the latter being cont-rolled in its closing and opening movements by mechanism not shown in detail, since it is substantially like the mechanism above described for controlling thejaw 52 of the toe gripper.

This mechanism includes a pin 100 projecting upwardly through a slot in the bar 94 and arranged to engage the block 46 to hold the jaw 98 initially in open position. Each of the openings 95 in the block 46 is so formed as to prevent movements of the corresponding side gripper bar 94 laterally of the shoe, but is sufficiently wide vertically to permit the bar to; swing lengthwiseof the shoe, as requiredfor tip straightening. To permit such swinging movement, each bar 94 is pivoted atfl102 to a slide 104 mounted. in a guideway in the bracket 58. a

Each of the opposite side grippers is operated through a separate friction clutch similar to the clutch hereinbefore described for operating the toe gripper. Each clutch comprises a clutch member 106 (Fig. 3) mounted for turning movement on a shaft 108 which extends transversely of the. bracket. 58, and

fast on each of the clutch members 106 is a pinion 110 in engagement with rack teeth formed on the lower face of the corresponding slide 104 (Fig. 2). In engagement with one of the clutch members 106 is a co-operating clutch member 112 which is-fast on the shaft 108; andin engagement with the other clutch member 106 is a co-operating clutch member 114 which is mounted for sliding movement lengthwise of the shaft 108 but is forced to turn with the shaft by means of a pin 116 which a slot 118 in the clutch member. A spring 120 is mounted on the shaft 108 between the clutch member 114 and a hand wheel 122 that is threaded on the shaft and serves to adjust the tension of" the spring. It will be seen that the spring 120 thus tends to move the clutch member 114 and the shaft 108 in opposite directions, and thereby tohold both the clutch members 112 and 114 in engagement with their co-operating clutch members 106 with a force determined by adjustment of the -wheel 122. The members of each clutch are projects from the shaft into 7 mined degree of tension and will then be subjected to supplementary pulling impulses by reason of relative slipping movement of the "members of its operating clutch.

The means for operating the two opposite side clutches comprises a gear sector 124 in same spring 120, the upper will finally be subj ected to substantially the same degree of tension at the opposite sides of the forepart. Each of the opposite side gripper bars 94 has on its lower face, a lug 134 (Fig. 2) arranged to engage an adjustablestop 136 on the block 46 to determine the'initial position of the gripper and to cause the parts of the controlling clutch to assume their initial relation to each other before the machine comes to a stop at the end of the cycle.

As more particularly hereinafter. described, the machine is so controlled as to come automatically to a stop at the end of the upper-pulling movement of the grippers to permit the operator to inspect the work prior to the wiping and fastening operations, and the machine is provided with means which may be utilized while the machine is thus at rest for effecting relative movements of the opposite side grippers lengthwise of the last to straighten the tip. This means comprises a hand lever 138 which is fast on a rock shaft 140 having thereon oppositely disposed eccentrics 142 connected by links 144 to the respec tive side gripper bars 94. Movement of the lever 138 in one direction thus serves to move the opposite side grippers respectively in opposite directions lengthwise of the shoe to adjust the upper. It will be understood that the friction of the parts and the character of the eccentric connections are such as to retain the side grippers in adjusted position.

After the upper-pulling operation the upper is subjected at the end of the toe and at the sides of the forepart to an upwiping operation, after which its margin is wiped inwardly over the bottom of the last in these different locations into position to be fastened. The wiping means is mounted on the block 46 which, for this purpose, is provided with a front arm 146 extending forwardly over thetoe gripper .and with opposite side.

arms 148 extending forwardly adjacent to the side grippers. On the front arm 146 there is mounted for sliding movement toward and from the toe of the shoe a wiper 150 compris-' ing aplate having its inner end faced with comparatively soft material, such as leather, for engagement with the upper to upwipe the upper toward theedge of the last bottom. Adjacent to the wiper 150'there is mounted a wiper 152 for wiping the upper inwardly over the bottom of the last, this wiper having its inner end turned rearwardly to guide it over the edge of the shoe bottom. Spring plungers 154 press the wiper 152 against the wiper 150 while permitting'thewiper 152 to .tip in response to resistance of the shoe materials as it is moved inwardly over the shoe bottom. In each of the side arms 148 there are similarly mounted an upwiping'wiper 156 and an overwiping wiper 158, these wipers, except as to width and end contour, being substantially like the wipers 150, 152 at the end of the toe. Each of the wipers 158 is controlled by spring plungers 160 in the same manner as the toe end wiper 152.

The Wipers 150 and 156 are moved inwardly against the upper,v by mechanism hereinafter described, while the upper is held under tension by the grippers, and "thereafter the upwiping operation is effected by rearward movement of the block 46 which carries the wipers. For this purpose 'the block 46 is secured to rods 162 which are mounted for horizontal sliding movements in bearings formed in the frame of the machine. For imparting to the block 46 its rearward upwiping movement it is connected by a link 164 toa bell crank lever 166 provided with a roll 168 engaged by a cam formed in one side of the cam wheel 76.

For moving the wiper 150 downwardly into engagement with the toe end of the shoe, there is'mounted on an upward extension of the arm 146 a slide 170 having thereon an arm 172 which is forked for engagement with pins 174 projecting from opposite sides of a block 176 slidingly mounted on a. rod 178 which projects upwardly from the wiper 150. The block 176 is mounted between a nut 180 on the rod 178 and a spring 182 through which movement is imparted yieldingly to the wiper 150. The slide 170 is operated by a lever 184 which is pivoted at 186 on a bracket 188 extending upwardly from one of the side arms 148', one end of the lever being forked to engage a pin 190 projecting from the slide 170. The lever 184 is swung downwardly against the resistance of a spring 192, to move the Wiper 150 into engagement with the shoe, by means of a cam 194mounted on the upper end of a shaft 196 which turns in bearing's'forme-d in the bracket 188, the cam 194 being arranged to engage a. roll 198 on the lever. The shaft 196 at its lower end is connected by a universal joint to a. telescopic shaft200 which is connected in turn by a universal joint to a shaft 202 mounted in a bearing on the frame of the machine. Fast on the shaft 202 is a pinion 204 operated by a rack bar 206 which is provided at its rear end with a roll 208 engaged by a cam formed in one side of a cam Wheel 210 which is fast on the shaft 78. It will be understood that this cam serves, through the connections described, to move the wiper 150 into engagement withthe shoe, and that by means of the telescopic shaft 200 and the universal joints at the opposite ends thereof, operative connection between, the cam and the lever 184 is maintained in all positions of the movable block 46.

A portion of the mechanism above described for moving theend wiper 150 downwardly ,is also utilized to move the side wipers 156 into engagement with the shoe. For controlling one of the side wipers there is provided a transverse rack bar 212 operatively' engaged at one end by a pinion 214 on the shaft 196 and engaging at its other end. a pinion 216 on a rock shaft 218. The shaft 218 carries a lever arm' 220 which is forked to engage pins 222 on the opposite sides of a block 224 slid; ingly mounted on a rod 226 which is fast on the wiper 156, a spring 228 being interposed between the block 224 and the wiper for im- I parting inward movement yieldingly to the wiper, and the rod 226 having a nut 229 thereon to be engaged by the block 224 for moving the wiper outwardly. The opposite side wiper 156 is moved inwardly toward the shoe by similar mechanism, comprising a lever arm 220 and a spring228, this lever arm being fast on the shaft 196. 1

The wipers 152 and 158 for wiping the margin of the upper inwardly overthe bottom of the last at the end and the sides of the forepart are operated by the same means which moves the upwiping wipers inwardly against the shoe. The wiper 152 has a laterallyprojecting outer end portion through which loosely extends a threaded rod 230 piv otally mounted on the wiper-operating member 172, this rod having nuts 232 thereon which are spaced from each other at opposite sides of'the projection on the wiper to provide a lost motion connection between the member 172 and the wiper 152, so that the wiper 150 may be forced yieldingly into engagement with the shoe and held in such engagement duringthe upwiping operation before the wiper 152 .is forced inwardly over the bottom of'the shoe. Between theside wipers 158 and the operating arms 220 there are similar lostmotion connections, comprising threaded rods 234 pivoted on the arms 220 and provided with spaced nuts substantially as in the mechanism provided for operating the end wiper 152.

7 Before the wipers 152 and 158 are forcedinwardly over the bottoml of the shoe, the toe and side grippers are made to release their hold on the upper. It will be understood that, at the beginning of the operative movement of the gripper bars 44' and 94, the pins 90 and 160', which are mounted on the rods which controlthe pivoted grioper aws ashereinbethe block 46 until the gripper jaws have been closed on the upper, whereupon these pins are moved out of engagement with the block 7 as the grippers are operated to pull the upper. The movement which the'block 46 thereafter receives in operating the wipers 150 and 156 to upwipe the upper carries it toward the pins 90 and 100 on the grippers, but'not so far as would cause it, under all conditions, to efiect'the opening ofthe gripper j awsby engagement with the pins. F or opening the gripper. jaws there are, accordingly, provided arms 286 which are pivotally mounted on the frame of the machine and are provided with inner end portions which lie in recesses formed in the rear face of theblock 46 be: tween the block and the pins 100 on the 'sidegrippers, as 'shownby dotted lines in Fig.

3. It will be seen that the ends of these'arms are extended far enough to project also by the opposite ends of the pin 90, on the toe gripper. Mounted in the block 46 are screws 238, the heads of which are arrangedtoengage the lever arms 236 near the fulcrum points of these arms and thus to impart to the arms, in the operative movement of the block 46, such swinging movement as to carry v their inner ends away from the rear face of i the block and thus cause them to operate on the pins and-100to open the toe and side grippers in the upwiping movement of the wipers 150 and 156. Preferably the screws 238 will be so adjusted as to cause the grippers to open and release the upper when the wipers have arrived substantially or. nearly at the end of their up-wiping move,- ment. The arms 236 are held in engagement with the screws 238 by springs 240.

For supporting the shoe against the pressure of the 'overwiping and fastening means there is provided a clamping device comprising an arm 242 mounted on the front end of one of the rods 162 hereinbefore referred to as movable lengthwise with the block 46;

The arm 242 carries a pad 244 of yie-ldab-le material such as rubber faced with leather for I engaging the shoe at the top of the forepart, and the arm is mounted to swing about-the rod 162 from an idle position in which the pad 244 is at one side of the shoe, asshown in Figs. 1 and 2, to a position in which the pad is in front of the forepart of the shoe. The hub of the arm 242 carries a projection 246 which is arranged to engage a lug 248 formed on a collar'which is fast on therod 162 to determine. the idle position of the arm, and a spring 250 is arranged to act on the projection 246 tohold the arm in idle position. The arm 242 is swung by theoperator into position to present the pad 244 in front of the shoe before the machine is start 2 l56-to upwipe the upper, the pad 244 is forced firmly into engagement with the shoe. The pad 244 is mounted on a bar 252 which is slidable in the arm 242, and a spring 254 acts on this bar to hold the. pad in retracted position. After swinging the'pad into position in frontof the shoe, the operator may push on the outer end of the bar 252 to move the pad toward. the shoe before starting the machine, the pad being held in the position to which the operator moves it by means of a pawl 256 in engagement with rack teeth formedon the bar 252. The comparatively shortmovement which the supporting rod 162 receives in the upwiping' operation then serves to force the pad firmlyinto engagementwith the shoe. In the return of the parts to starting position the arm 242 is swungtoone side by the spring 250 after the pressure of the pad 244 upon the shoe has been relaxed, and by means of a handle 258 the pawl 256 is made torelease the rod 252, thereby permitting the pad to here tracted by the spring 254.

For fastening the upper in pulled over position after the overwiping operation, the

machine herein shown is provided with means permanently positioned in a location opposite to the bottom of the shoe for driving a'single tack at the end of the toe and three tacks ateach side of the forepart through portions of the upper that are acted upon the wipers 152 and 158, these wipers being provided with slots'to permit the driving of the tacks, as shown by dotted lines in Fig; 1. One of the side tacking mechanisms is shown in detail in Fig. 5, thetacking mecha nisms at the opposite sides being identical except for differences in shape required by the contour of the shoe. Mounted for length.-

wise sliding movement in the block 46 and in the fix'edbracket 58 is awdriver bar 260 which carriesat its front end three tack holders or nozzles 262 and a corresponding number of tack drivers 264 within the holders. The tack holders 262 are 'slidingly mounted in-sockets formed in a; driver block or head 266 which is carried by an enlarged end portion of the driver .bar 260,-theblock 266 havmg which form bearings'for the tack holders and are engaged by enlarged heads 27 O on the threaded therein sleeve members 268 inner ends of the holders to limit outward movement of the latter. The drivers 264 are providedwith heads 272, and between these heads and the heads 270 on'the tack holders arecmounted springs274fwhich tend toretract the drivers and at the same time force the tack holders outwardly in the block 266. In-thetack-driving operation the driver bar 260 carries the ends of the tack holders 262 into engagement with the corresponding wiper plate 158, and by continued movement then forces theblock 266 and the drivers 264 toward-the shoe to drive the tacks.

ig-eezese.

i In order to'facilitate: the delivery of tacks to the-tack holders262, the-latter are mounted for tipping or turning movement fom their substantially horizontal tack-driving positions, as illustrated invFi g. 5, to substantially vertical tack-receiving. positions, as shown in full lines in Fig. 4. For this purpose the block 266 is provided with an arc-shaped flange 276 which is movable in. a corresponding guideway formed in the head portion of the-bar 260, and on the block are. provided a series of gear teeth 218 in engagement with the teeth oi a rack bar 280 which is slidingly movable in the block 46 and extends also through: a guideway in the head ofthe bar 260.. .The normal position of the rack bar r rack bar 280 on the teeth 27 8 into the position 7 illustrated, in Fig- 4, in which the'outlet. ends of. the: tack. holders 262 are directed vertically upward into position to receive tacks dropped.

When thedriver bar260 is moved toward the'left from the position in whichfit is shown in Fig; 4, thetack. holders areswung downwardly to horizontal position, this swinging movement of the tackholdeis being limited by engagement of a lug 288 on the block 266 with a lug 290 on the end of the rack bar 280. In thet'ack-driving operation the driver bar 260- is moved, farther to ward the left from the position of Fig. 5 and in this operation the rack bar 286 is carried along with the driver bar against the re sistance 01" its spring 284. v

v The mechanism for driving thetack at the end ofthe toe difiers somewhat in detail from the mechanism for driving the side tacks, as illustrated in Fig. 6. Slidingly mounted in the block 46 is a toe driver bar 292 immediately under the-toe gripper bar, 44, the bar 292 carrying at its front end a driver block 294 in which" is slidingly mounted atack holder 296 and a driver 298' in substantially the same manner as the correspending parts for driving the side tacks, as

illustrated in Fig. ;'The driver block 294 is pivoted at 300 on theend oi the bar 292, and in the tack-driving operation occupies a Inn position partly within a recess 302in-the it driverbar with the tack holder substantially Y horizontal, as shown in Fig. 6.

In Fig. 6 the parts are shown in the positions which they assume the tack holder is being moved horizontally toward the shoe, the rod 306 being carried along It will be. underried into engagement with the toe wiper plate 152, and that by continued movement of the driver bar the block 294 and the driver 293 are moved relatively to the tack holder to driver to a substantially vertical position to receive the tack, as shown in full lines in Fig. 4. To provide space for the upwarc swinging movement. of the toe tack holder 296, the toe gripper bar 44 and the rod 56 therein are provided with slots extending lengthwise thereof, as indicated by dotted lines at 311 in Fig. 4.

.The means for delivering the tacks to the several tack holders through the flexible tubes 286 may comprise any suitable tackseparating and delivering mechanism, and accordingly such mechanism is not shown herein indetail. In Fig. 8 is illustrated one form of device which may be utilized to invert the tacks so as to deliver them head downward. This device comprises an oscillatory member 312 provided with a plurality of tack-receiving recesses 314 corresponding in number to the number of tacks to be driven at each operation, the tacks being delivered point downward to these recesses from suit able separating mechanism through tubes 316. The member 312 isturned ata predetermined time in the cycle to drop the tacks head downward into the flexible tubes 286.

: The mechanism for operating the driver bars 260 and 292 comprises a bell crank lever 318, the upper end of which is forked, as shown in Fig. 3, for engagement with the opposite ends of a pin320 which extends through both the opposite side driver bars 260. Carried by the pin 320 is also a bracket 322 which is fast on the rear end of'thetoedriver bar 292. It will thus be seen that the three driver bars are operated simultaneously by the lever 318. On its lower end the lever is provided itha roll 324 engagedby a cam "formed in one side of the cam wheel 132'.

For operating the cam shaft 78 and for controlling the operation of the machine any suitable means maybe utilized, a convenient arrangement of mechanism for this purpose Mounted for turning movement about a sleeveon the shaft 78 is abelt pulley 326 which is formed to serve as one member of a clutch, anda cooperating clutch member 328 is splined on a sleeve 330 on the shaft, a spring 332being provided forholding this member out of enby the pulley 326, the shaft 78 is turned at i a considerably lower rate of speed than the pulley by reason of the-relative sizes of the different gear wheels.

The clutch member 328 is forced into engagement with the pulley 326 by means of a vertically movable wedge member 342 connected to a lever 344 which is acted upon by a spring 346 to force the wedge member downwardly andt-hus toset thecl'utch', and

is provided with a brake shoe 348 for engagingthe member 328 to stop the machine when the clutch is released: As the parts are positioned in Fig. 7, the lever 344 is held in its uppermost position with the brake applied and the clutch released. For holding the lever 344 in this position there is provided a lever 350 having thereon a roll engaged by a stop cam 352 on the cam shaft 78, this lever having projecting therefrom an arm 354 which acts through .a pair of toggle members or links 356 on'an arm 358 projecting from the lever 344. It will be seen that, as-the parts are positioned in- Fig. 7 the togglemembers 356 are in alignment with each other so that rigid connectionis'provided between the arm 354 and the arm 358. In order to start the machine, there is provided means for breaking the-toggle 356, thus releasing the lever 344 to the action of its spring 346, one of thetoggle members 356 having therein a slot 360 which forms part of the connection between it and the arm 354 and affords suflicient play to permit the breaking of the toggle. The breaking of the toggle is effected by means of a treadle 362 which actsto, raise a treadle rod 364 against the resistance ofa spring 366, this rod having upon its upper end a member 368 which engages the lower end of a vertically slidable rod 3. 0 and acts to raise this red againstthe resistance of a spring 37 2 when the tr eadle is depressed, the rod 370 being connected to the knee joint of the toggle by means'of a link 374. V

Immediately-upon the starting of the machine the lever 350 is released by the cam 352, so that the arm 354 is swung to the left far enough to permit the straightening of the toggle 356 by the action of the spring 372 when the treadle is released by the operator. A 'igld connection between the-lever35O and lever'344 is thus reestablished, so that stop at this point, even though the operator I 1 lease the latter.

should continue to hold the treadle depressed.

F or this purpose-the member 368 is pivot-ally mounted. on the rod364to permit it to swing out from. under the rod 370 andthus to re- Such swinging movement of the member 368 is eflected immediately after the starting of the machine bythe action of the stop cam 352 (or later the stop cam 37 6). on a lever 37 8,. this lever being connected by a link 380, crank arms 382 and 384, and a link 386 to the member 368. lVhen the'lever 378 is released by the cam, a spring 388 swings the member 368 back again into position for it to project under the end of the rod 370 when the operator releases the treadle. f V

In the operation of the machine, briefly I summarized, the operator adjusts the shoe rest for the size and style of shoe upon which open gripper jaws.

rearward movement.

the machineis to operate, and presents the shoe in the position illustrated in Fig. 2 with the margin of the upper projecting within the lVhile supporting the shoe with one hand, the. operator depresses the treadle 362 to: start the machine, whereupon the gripper bars- 44 and 94. begin their As the gripper bars start their rearward movement, the spring 88 in the toe gripper bar and the corresponding springs in the side gripper bars act to close the machineis brought automatically to'a. stop by the action of the stop-cam 37 6- on thelever 350."

The operatoris then enabled to inspect the shoe and to make any tip straightening adjustment that-may be needed by manipulation of the lever 138. I

Before starting the machine for the second time, the-operator sw ngs the shoe-supporting pad 244: into position in front of the shoe and moves the pad-forwardlytoward, and it may be substantiallyinto engagement with, the

'. shoe, by pushing on-thebar 252. He then again depresses the treadle to start the machine, whereupon the wipers 150' and 156 are moved mwardlyuntoengagement with the shoe at the toe end and at the sides of the forepart at a substantial distance from the edge of n the shoe bottom, as illustrated in Fig. 10.

The wiper-supporting block 46 is-then moved toward the rear, thus imparting to the-abovementioned wipers upwiping movement toward theedge'of the shoe bottom. 'Near the end. of this upwiping movement of the wipers the grippers are made toopen and release the upper by the action of the arms 236 on the pins 90 and 100. By further movement of the wiper-operating means the wipers 152 and 158 are then forced inwardly to wipe the margin of the upper over the insole, as illustrated in Fig. 11, the holding pressure of the wipers 150 and 156 onthe upper being simulta neously increased to insure against loss of tension. I

After the upper has thus been wiped inwardly over the insole, operative movement is imparted to the tacking mechanism to as-- ten the upper. In this operation the tack holders 262 and 296 are moved horizontally toward the shoe and into engagement with the wiper plates 158 and 152, and by continued movement of the driver bars7260 and 292 the tacks are positively driven into the shoe to the required distance. Thereafter the parts of the machine begin their return movements to starting position. 'In the return movements of the tacking mechanisms. the tack holders are tipped upwardly to vertical positions in the manner hereinbefore described to receive tacks which are then delivered into their outlet ends, and byreverse' movement-of the. driver bars the holders are then tipped downwardly to horizontal positions ready to operate on the next shoe. "In the return of the wipers to starting position, they are first moved outwardly away from the shoe and are then carried forwardly by movement of the block 46. Itwill be understood that at thetime when the tack holders are tipped upwardly into tack-receiving position the block 46' is held stationary with its tack-delivering openings in alignment with the respective tack holders. 1'

It should be'understood that for the ias tening of the upper the invention is not'dependent upon the use of tastenings or the V particular form herein shown, and the term tack and similar terms are accordingly.
